Suppose you have a paper cup floating in a measuring cup that contains water. When the paper cup is empty, the water level in the measuring cup is at 250 ml. When you put 10 quarters in the
paper cup (which is still floating), the water level in the measuring cup is at 300 ml. What information about
a quarter can you deduce from this experiment?

step-by-step explanation:

80° is the measure of gh

step-by-step explanation:

circle f is congruent to circle j

we have two circle with center f and j.

both circles are congruent. the radius of the circle would be equal.

see the attachment for the circle.

we are given ∠efd ≅ ∠gjh

therefore, arc (ed) = arc (gh)     (∴ circle f is congruent to circle j)

but ∠dfe=80°=arc (ed)

therefore, arc (gh) = 80°

thus, 80° is the measure of gh
